Plasma is a state of matter which is made of charged particles. Serving to be one of the four fundamental states of matters. Instead of having molecules, it is made up of free elctrons and ions, as it cannot mantain or have a fixed shape, mass or volume. Highly reactive to magnetic fields.
Even though plasma is a chaotic element of its own. Caused by very high temperatures. It still can be converted back to the 3 other forms of matter if enough energy is lost. As ion and electrons will combine to form atoms or molecules to create a substance again. This is known as "Recombination", occurs when plasma tends to be cooled, generally forming back into gas.
